To all whom it may concern:

Be it knownthat I, VERNON E. PAnR sH, a citizen of the United States, and residing at Cupertino, in the county of Santa Clara and State of California, have invented certain new and useful Improvements, in Machines for Ridging Land, of which the following is a specification. v

In certain methods of irrigating lands, particularly orchard lands and the like, it is customary to throw up intersecting ridges of earth to form rectangular reservoirs whereby a given area 'of land may be flooded with water independently of adjoining areas. In orchard irrigation these rectangular reservoirs are formed about each individual tree so that even insmall acreages a large number of these reservoirs are required. a

It is the object of my invention to provide a'device for ridging land for irrigation or other purposes that will effectively form rigges of desired height and width; that w' cut through and ridge over crossing aths or roads; that can. be maintained to orm a required ridge in soft ground; and that can be equipped with a compacting device for theridge after it is formed. A further object isto provide a compacting device to cooperatewith said ridge forming-machine, .and to providea machine of the character indicated that will'be simple inform and operation i and highl eflicient in its practical application.

In the drawing: 1 V

Figure 1 is a plan view of the machine with the compacting device mounted thereon. Fig. 2 is a side elevation of the machine as shown in Fig. 1. a

Fig. 3 isa diagram illustrating the results secured by the machine forming the basis of this invention. v I

Referring more particularly .to the drawing, 1 indicates the frame of the machine provided withmeans at 2 for connecting the same to a tractorand having the rear cross member 3 raiseda-distance as shown so that it will not engage the ridge formed by the machine. The rear member 3 and the sides of frame 1 are connectedby angular portions 4 provided with a series of orifices 5 inwhich are mounted hangers'6 carrying disks 7., Iii-bearings 8 on frame 1 are crank axis 9 carrying wheels 10 on their outer ends and provided with handles 11 on their inner ends. At 12 are shown notched sectors mounted on frame 1 adjacent levers 9 whereby the said levers may be locked in a given position by means of locking device 13.

For transporting the machine, the lever 9 is thrown into the position shown in Fig. 2 and locked in said position by means of mechanism 12-13, with frame 1 and the parts carried thereby in the raised position shown. When, however, it is inuse to form a ridge or ditch, the lever 9 is thrown forward and locked in a forward position such as indicated in dotted lines at 14. This movement operates to lower frame 1 with relation to wheels 10, thereby causing disks 7 to enter the ground as shown in dotted lines at 7. IThe angular position of the disks as shown operates to cut furrows as 15 and throw the soil removed therefrom toward the draft line of the machine and substantially higher than the general level of the ground as indicated at 16,. the width of this ridge being determined by the osition of disks 7 on angular members 4 a ong which the said disks are adjustable by means of hangers 6 and orifices 5.

It is important to position the wheels with proper relation. to the disks, "particularly when the ground is'irregula'r, or ridges are being crossed to form square checks. The

wheels should be arranged substantially in the transverse plane of the disks, preferably with their centers slightly ahead of the hangers 6 of the disks. Thereby, when the drawbar rises dueto the drive wheels of the tractor going over a high point in the land, the elevation of the disks is not perceptibly changed, as it would be in case the wheels were set too far ahead of or behind said disks. The crank axles are so disposed that little orno change occurs in the relation between the wheels and disks, regardless of changes in the elevation of the disks.

It is also important to have the wheels independently adjustable, as thereby the machine can be usedfor building ditches. This is done by forming two parallel ridges, the second ridge being made with one wheel of the machine runmn in the furrow, or slightly on the side of t e first ridge. The disk in this side must therefore be lower than the opposite disk, which is accomplished' through the independent adjustment of the wheels.

In a device of this kind the disks 7 are so mounted and positioned that when once set to cut for a given depth they will throw up a uniformly regular ridge even though soil of varying character may be encoun tered.

It-is desirable to apply some pressure to the side walls 17 of the ridge formed as hereinbefore described, whereby the same may be compacted, and large lumps of the soil broken up thereby preventing the formation of openings which would permit the passage of' water through the ridge. To effect this desired result.Iprovideapair of disks 18 so positioned that their inner surfaces bear against 'wal1s 17.' These disks are held in position by m'eans of yoke 19 and arms 20, the latter being connected to frame 1 as shown. As the ridging machine moves for- Wardthe disks rotate on bearings 21 and press against walls 17 at the same time thereby combining a grinding action with pressure and. efiiciently shaping and compacting the saidwalls.

It-is understood of course, that the machine may be used with or without the compacting device, and that changes in form, proportions, details of construction and mode of operation may be made within the scope of the appended claims.

I claim:

1. A machine for ridging land including aframe, plowing means mounted upon each side thereof and within the same and arranged to turn the plowed soil inwardly toward the draft line of the machine, a lever operatively mounted upon each side of said frame forwardly of said plows, each lever-havin its o'uter end extending backwardly'in su stantial parallel relation to the said draft line to a point in substantial alinement withsaid plows, a wheel operatively mounted on each backwardly extending portion of said levers and adjacent one of said plows, and means for locking each lever in a predetermined position.

2. A device for ridging land including a substantially open frame, supporting devices for said frame, means for adjusting said frame with relation to said supporting devices, plowing means mounted upon said frame on each side of'the draft line thereof and extending a distance within said frame whereby the plowed soil may be turned inwardly toward said draft line from both sides-thereof, said frame having a raised portion in the rear thereof to prevent engagement thereof with the ridge raised by said plows.

3. A machine for ridging land, including a frame, supporting devices for said frame, means for adjusting said framewith relation to said supporting devices, plowing means mounted on said frame arranged to turn the plowed soil into a ridge along the draft line of themachine, and means cooperating with said machine for compacting the ridge formed by Said machine, said means comprising a frame connected to. the rear of said first mentioned frame, and apair of disks pivotally mounted thereonand having their inner surfaces arranged to engage the sides of the ridge formed by said machine.
